Hi dsdoyle,

Let us isolate the problem. Kindly answer the questions below:

a. Have you tried to swap the WAN connections then observe if same problem occurs? Connect the Brighthouse connection to WAN2 port then connect the WAN2 connection to the WAN1 port.

b. Are both WAN connections subscribed to Brighthouse?

c. Is the device from Brighthouse a modem-only device or a combination of modem-router?

d. Have you tried to factory reset the FVS336Gv3 then reconfigure the settings from scratch and observe if same problem occurs?

Also, kindly try to uncheck "Block UDP Floods" under Attack Checks shown on the image below then check if same problem occurs.

I look forward to your response.

Hello,

Sorry to have taken so long to get back.

1. I have not swapped WAN1 fro WAN2 because I cannot afford/risk to have my client down again. I have moved the BrightHouse connection directly to the Netgear modem (which has also had intermittent problems.

2. The Brighthouse device is a Ubee modeom/router combo set to bridge mode

3. One connection is Brighthouse and other is Earthlink.

4. Firmware is update on both devices.

5. Block UDP Flood was already unchecked. Any other ideas?

Please advise.

Thanks for your help,

Don

Hello dsdoyle,

I believe the best way to isolate the issue is to swap the connections between the two WAN ports or connect a device directly to the Brighthouse modem and see if it will give you the same issue. Before changing any settings on the router, it is best to know if the connections coming from the modems are working properly. How often does the disconnection happen? Is there a large number of users when this happens?

Looking forward to your response.

Thanks,
